Vibration is how a drive train tells you something is wrong. A propeller blade touched on a mooring line, an engine mount that has settled, a shaft that's out of line or a worn cutless bearing all show up as vibration first, then as wear on seals, bearings and gearboxes.
We look after the whole path from gearbox to propeller: shaft alignment, couplings, bearings and seals, propellers, waterjets, and the steering systems on motor and sailing yachts.
Alignment between engine, gearbox and shaft checked and corrected, including engine mounts, couplings and intermediate bearings.
Removal, inspection, repair coordination and refitting, plus fouling and damage checks at haul-out.
Marine gearboxes including ZF Marine: oil, coolers, engagement and shift problems, and drive systems.
Waterjet propulsion including Marine Jet Power (MJP) and Rolls-Royce (KaMeWa) units: inspection, wear parts and steering and reversing gear.
Rudders, rudder bearings and steering gear, including Jefa and Lewmar steering on sailing yachts.
Shaft seals and stern-tube bearings inspected and replaced, best planned with a haul-out.
| What you notice | Usual cause |
|---|---|
| New vibration at certain rpm | A damaged or fouled propeller, misalignment, a worn cutless bearing or a tired engine mount. |
| Water coming in at the shaft seal | A worn seal or a seal damaged by vibration. Keep an eye on the bilge and get it checked straight away. |
| Clunk when engaging gear, or slow to engage | Idle speed, gearbox oil level or condition, the shift cable or control, or a coupling problem. |
| Top speed down at the same rpm | A fouled hull and propellers, propeller damage, or, on waterjets, wear or debris in the impeller. |
| Heavy, stiff or vague steering | Rudder bearings, steering cables or linkages, or the hydraulic steering itself. |
| Gearbox temperature alarm | Low oil, a blocked oil cooler or a cooling-water problem. |

Other brands we service
Busy summer harbours and anchorages mean mooring lines, lost ropes and floating debris, and they all find propellers. A small ding that adds vibration is easy to put up with for a season. It costs more later in seals, bearings and gearbox wear.
The more of this we have, the better our chances of arriving with the right parts. The online booking asks for it step by step.
Book online, upload photos of the problem and our AI technical assistant asks the follow-up questions an engineer would ask. Our team receives a structured job brief, so the right technician arrives with the right parts.

The work
Per quote
Certified engineers carry out the job as quoted, using quality parts and meeting the relevant compliance requirements.
Testing and follow-up
Ongoing
We test what we've worked on, hand over the documentation and stay available if anything comes back.
The usual causes are propeller damage or fouling, shaft misalignment, worn cutless bearings and settled engine mounts. We work out which it is before recommending a fix, and some fixes can be done afloat.
Alignment is often checked and corrected afloat, since that's how the yacht sits in service. Propellers, cutless bearings and some shaft-seal work need a haul-out.
ZF Marine, Rolls-Royce (KaMeWa), Marine Jet Power (MJP), Evolution Marine, Jefa Steering and Lewmar.
Yes. Watch the bilge level, make sure the bilge pumps are working, and call +34 971 251 374. If water is coming in faster than the pumps can clear it, treat it as an emergency.
Yes: waterjets including Marine Jet Power (MJP) and Rolls-Royce (KaMeWa), covering inspection, wear parts and the steering and reversing gear.
